Letters Patent No. 113.531idated April 11,'18711 y IMPROVEMENT IN SAWlNG-MACHIN'ES.

The Schedule referred to in these Letters Patent and making-part of the same.

To all whom 'it may concern:

Be it known that we,P11IN EAs F. KING and ED.

WIN A. KING, of St. Louis,"in the county ot'St. Louis and State of Missouri, havemade certainnew and useful Improvements in Machines for Sawing Straight, Angular, and similar irregular Work; and we do hereby declare that the following is a full and true description thereof, reference being had tothe acceuipanying drawingand to the letters of reference marked thereon. v

This invention relates- First, to such a construction of the broad slide that the same, in Ycombination with an adjustable gauge, -shall be adapted for all mannerA of straight as well as acute angular ripping purposes; v

Secondly, to the arrangement -of .additional slides, in combination with apgauge and saw-table, for accomplishing all kinds of initering, .bevelin'g, and rab-v beting purposes;

. Thirdly, to the arrangementof parts for regulating the stop motion oi' the slides; and

Lastly, to the arrangement of a protractor for fapilitating' angular work, and to certain detail construcappear.

To enable those herein skilled to make and use our said invention, we will now more fully describe the same, referring to tlieaccompanying- Figures 1 and 2, respectively, as top plans; to

Figure 3 as an end view; and to Figure 4 as a perspective view of detail parts for regulating the stop motion.

Upona suitable-metal frame, A, is secured the table B in any proper manner.

In said table B (formed either of wood or metal) the broad slide Ov is fitted to slide. Y y

The slide C has alsoa slide-rest, c, similar to the opposite rest l, fitted in the table B.' l Y In said slide-rests c and .b the parallel slides D rand D' are fitted to slide, as shown in figs. I and 2.

The saw-mandrel E, carrying .the saw E1 and driving-pulley e, we support in a suitable arhor,'E2, secured rmly within the side of theframe A. vProper belting, passing around the pulley e, .operates the saw E1 in manner usual. y

In order,4 however, that additional saws and cutterheads may be'secured to the mandrel E, the table B is suitably slotted at-B, as shown in figs. land 2( Suitable collars, e, secure the saws in proper position on the mandrel E.

In combination `with the slides C, D, and D', we arrange'the gauge E, made adjustable by corresponding slots, f, in which milled set-screws, F are fitted. Said tion of parts, all of which will hereinafter more fullyv gauge hasalso a thumb-screw, G, carrying a self'- marker, G', made adjustable by its slots g.

The front edge of said gauge F we provided with adjustable face-block, g', in manner usual, to allow the saw to cut entirely through the stuff'.

For ripping,'splitting, straight-sawing Work, and the like, the lbroad slide G is used, the narrow slide D bei-ng dispensed with. y

In order to gauge the ont with reference to thesaw E, the broad slide G has also small slides, c1, tted to slide in proper transverse grooves, as shown in igs.- 1 and 2'. v

The gauge rl' being, therefore, properly secured to the small slides o, as shown in Iig. 2, (said slides for this purpose having holes, c2, in which'lthe screws F' engage,) the operator is readily enabled to rip or saw all manner of straight worlnraud to feed the material (by adjusting the guide or gauge accordingly) so as toI saw thickor thin, as desired; also, it isplain that, as

ing, rabbetiug, and other similar irregular saw-work,

the parallel slides D D are used in combination with Vthe gauge Il, as shown in ig.,1, the broad slides G being'secured stationary to thetable Bvby proper end setscrew O.

To adj ust and secure the gauge F in the various required angular positions on the slides'D D', the same arel provided, respectively, with fa series of holes, al,

f other angular work with accuracy, we ,have provided the table B with an ordinary protractor, H, numbered in both directions at right angles with the saw El, in manner indicated in figs. l` and 2.

By such an arrangement -of parts the operator is readily enabledto adjust and secure the igauge F to V guide the stuff to be sawed at any angle indicated by the protraotor H. -It `erilllalso be observed, by the arrangement of parts, that the self-marker G can at the same time be adjustedto any point from the saw as the case requires, for sawing equaldistanc'e's, or for accomplishing long and short cuts.

To regulate the stop motion of the parallel` slides D D said slides, at their rear ends, have slots, I, re- Y spectively, in which a set-screW,I1, carrying a.stop. block, Iz, is arranged adjustable, as clearly shown inl detail in g. 4.

By simply adjusting the stop-block I2 in position, (on either of the slides D D',) the movements of said slides and gauge F can be regulated within various positions from the saw, and thus the material can be sawed or cut to accurate distances.

Our improved machine in its operation `accomplishes all kinds of cutting, ripping, jointing, beveling, rabbeting, miterng, and similar irregular'w'ork with the greatest precision and accuracy, saving time ordinarii Y jy consumed inV measuring, planning, laying, out,.andV

otherwise in its use is cheap and durable.

Having thus fully described our said invention, What We claim, and desire to secure by Letters I `Patent, is-

l.. The arrangement of the parallel slides D D' with adjustable stop-block I, for regulating the .stop motion of said slides, in combination with the gauge F, substantially as set forth.

2. The gaugeF, small slides c1, when combined with the broad slide C, table B, arbor and saw attachments E El, frame A, and arranged to operate substantially as and for the purpose set forth.

3. The parallel slides D D', having slot-s I, stop motion-regulating devices IPI?, gauge F, protractor H, when arranged in combination with the broad slide I(l, table vB, saw E1,'arbor E, and frame A, to operate for sawing angular and irregular Work, as described.
